Hoosiers, having been spoiled by this week's near-record warmth, will get a rude awakening beginning Friday, as the leading edge of a vast pool of chilly air pours over Indiana.
This chilly air promises to bring Indiana its lowest temperatures of the season thus far.
Temperatures Friday will hold up to 25 degrees below the balmy upper 70s and lower 80s reached on Thursday.
Put another way, highs will be in the lower to mid-50s in most of northern and central Indiana.
Indianapolis hit 78 degrees on Wednesday, and was expecting at least as high on Thursday. Friday's forecast was for a high of 54 degrees under rainy skies.
The agent for change, a cold front plowing into the Midwest from the Great Plains, will cross the Hoosier State with a band of rain and even thunderstorms Thursday night and early Friday.
Slowing of the front west of the state will allow rainy weather to linger in the afternoon in central and eastern Indiana.
Meanwhile, the coldest weather will not begin until early next week, when all but southernmost Indiana can look forward to highs in the 40s.
Cooler temperatures and lower humidity continue through late-week, despite the return of thunderstorms.
